Notes:
- If you place this "Automated Step" in the Workflow diagram,
    - the request will be automatically sent every time the process token arrives.
    - A request is automatically sent to the OpenAI API server. (REST API)
    - The response from the OpenAI API server is automatically parsed.
    - You can incorporate "AI assistance" into your business processes.
- Audio File: Assume that the file for storing FILE type is the audio source.
    - The first file is used as the audio source.
    - The second and subsequent files are not referenced.
    - Audio file to transcribe
        - "mp3", "mp4", "mpeg", "mpga", "m4a", "wav", or "webm"
        - Video files (mp4, etc.) are also supported.
        - Consider the size limit on the API side.
            - Status 413: "Maximum content size limit (26214400)" (about 26MB) (as of 202303)
        - Note: Upload in Questetra BPM Suite is limited to 100MB (as of 202303)
- PROMPT: Text to improve the quality of the generated transcripts
    - The PROMPT should be in English.
    - Summary text for reference in English translation
        - Words or acronyms that the model often misrecognizes in the audio
- An API key is required to use the OpenAI API.
    - Get an API Key in advance.
    - Set "Secret API Key" to "HTTP Authz Setting" (Token Fixed Value)
